Cheshire Cat

Why is the Cheshire Cat important?

I don't really know except that he makes another rather interesting and "mad" creature Alice meets up with. He also tells her which way to go (It doesn't matter which way you go if you don't know where you want to be!) But does tell her which way to go to get to the Mad Hatter.

I think he is kind of a "guide" for Alice. He gives her some direction and insight.
